Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters,... view more (2004-05-13)

Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon... view more (2002-09-12)

Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide   view more (2006-04-13)

UA scientists part of Supreme Court case on carbon dioxide emissions
Four faculty members from The University of Arizona in Tucson were part of an amicus curiae brief supporting the plaintiff in today's historic U.S. Supreme Court decision on carbon dioxide emissions and climate change.   view more (2007-04-03)

Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the... view more (1999-01-28)

Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today.   view more (2007-12-11)

Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common... view more (2001-06-21)

Tiny 'cages' could trap carbon dioxide and help stop climate change
A natural physical process has been identified that could play a key role in secure sub-seabed storage of carbon dioxide produced by fossil-fuelled power stations.   view more (2006-03-17)

Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them... view more (2005-05-05)

KTH research: Increased combustion reduces carbon dioxide emissions
New, previously overlooked technology could dramatically reduce emissions of carbon dioxide. Bio-energy facilities that capture carbon dioxide from combustion gases would even make it possible to reduce the amount of carbon dioxide in the atmosphere. The idea of capturing carbon dioxide and storing... view more (2001-11-23)

TREATING POLLUTED LAND WITH CARBON DIOXIDE
First a granular binder containing products which react with carbon is added to the contaminated soil and then carbon dioxide is pumped into the mixture. The three components rapidly combine to produce a cement that is very stable, and although marginally more expensive is immediately available for... view more (1999-11-25)

Climate change will affect carbon sequestration in oceans, model shows
The direct injection of carbon dioxide deep into the ocean has been suggested as one method to help control rising carbon dioxide levels in the atmosphere and mitigate the effects of global warming.   view more (2005-09-08)

First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions.   view more (2007-11-15)

EARLY PROMISE OF SIMPLE TEST FOR DIAGNOSING MALIGNANT HYPERTHERMIA (p 1579)
German authors of a research letter in this week’s issue of THE LANCET describe the potential of a straightforward test for identifying people at risk of the often fatal reaction to general anaesthetics, a syndrome known as malignant hyperthermia. Malignant hyperthermia (MH) is a... view more (2002-05-01)

New Separation Technology With Carbon Dioxide Is Cleaner And Cheaper
Researchers of Wageningen University and Research Centre in the Netherlands have developed a new clean, process to isolate valuable or undesired components from solids, such as components for food products. In contrast to other conventional processes, the new invention concerns a continuous process... view more (2004-07-05)

Deep sea algae connect ancient climate, carbon dioxide and vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45-25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science... view more (2005-06-23)

Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial.   view more (2007-05-10)

CT colonography even safer than previously reported, says study
The safety profile for CT colonography (CTC) is extremely favorable, particularly for the purposes of screening patients with no symptoms and when distending the colon using an automated carbon dioxide technique, a finding that goes against the higher complication rates for CTC reported by other... view more (2006-05-02)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science.   view more (2006-12-08)

Mice use specialized neurons to detect carbon dioxide in the air
For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby.   view more (2007-08-17)

Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.   view more (2008-01-03)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.   view more (2007-10-23)

Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming.   view more (2005-10-13)
